What this means

The Speed River near Armstrong Mills is running below normal at 1.06 m.

It has dropped 0.01 m over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 0.99 m and 1.08 m.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that.
